Environmental groups have sued the U.S. Bureau of Land Management (BLM), claiming that BLM’s review of potential environmental harms under the National Environmental Policy Act (NEPA) was deficient. Southern Utah Wilderness Alliance, et al., v. United States Bureau of Land Management, et al., Case No. 2:13-cv-00047-BCW (D. Utah). BLM granted a permit to Gasco Energy allowing it to drill nearly 1,300 gas wells on 200,000 acres of federal land in northern Utah’s Uinta Basin. Gasco’s permit requires it to institute environmental controls imposed by both BLM and Utah state agencies. The environmental groups, however, claim that BLM’s review of the project’s impacts to air pollution was deficient and that the drilling will adversely impact threatened or endangered species and wilderness lands. The complaint seeks a court order prohibiting development until BLM performs a new environmental analysis.
